Definitions
- the present disclosure relates to transmission schemes in wireless communication systems, and in particular to a method and a device for paging transmission in a communication system supporting multiple numerologies.
- the various numerologies refer to various subcarrier spacings, various symbol time lengths, various Cyclic Prefix (CP) lengths, etc.
- CP Cyclic Prefix
- the overall design of the system physical layer would best adopt a unified structure for different numerologies.
- PF Paging Frame
- PO Paging Occasion
- an LTE network generally employs a single numerology or the numerology basically does not change in a long time in the network
- the definition of the possible time of paging using the PF and PO having a fixed time length can simplify the design of system, under the premise of guaranteeing the paging capacity and not increasing the power consumption of UE.
- a network supports different numerologies, thus, a given time length, for example, 1 millisecond, probably includes multiple basic scheduling units (for example, slot). If the legacy design of the current paging opportunity is employed, the UE would detect the paging message different times for different numerologies within the 1 millisecond. Therefore, power consumption in some numerology would be greatly increased. Meanwhile, the paging capacity varies greatly due to the adoption of different numerologies.

Abstract
Description
- This disclosure claims the priority benefit of Chinese Patent Application 201710255811.X, filed on Apr. 19, 2017, all of which is incorporated herein by reference.
- The present disclosure relates to transmission schemes in wireless communication systems, and in particular to a method and a device for paging transmission in a communication system supporting multiple numerologies.
- Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary session decided to conduct the study of New Radio (NR). The working item of 5G NR was agreed as an approved project to standardize the 5G NR at the 3GPP RAN #75 session.
- In order to be applied to various different application scenarios flexibly, future wireless communication systems, especially 5G NR, will support various numerologies. The various numerologies refer to various subcarrier spacings, various symbol time lengths, various Cyclic Prefix (CP) lengths, etc. In order to simplify the design of systems and to reduce the complexity of User Equipment (UE) implementation, the overall design of the system physical layer would best adopt a unified structure for different numerologies.
- In existing LTE systems, transmission opportunities of paging are defined through a Paging Frame (PF) and a Paging Occasion (PO) uniformly. The PF is a radio frame which is likely to transmit a paging message, and the PO is used for determining a subframe which is likely to transmit a paging message in the PF. The radio frame in LTE has a fixed time length of 10 milliseconds, and the subframe has a fixed time length of 1 millisecond. Since an LTE network generally employs a single numerology or the numerology basically does not change in a long time in the network, the definition of the possible time of paging using the PF and PO having a fixed time length can simplify the design of system, under the premise of guaranteeing the paging capacity and not increasing the power consumption of UE. Under the 5G NR, a network supports different numerologies, thus, a given time length, for example, 1 millisecond, probably includes multiple basic scheduling units (for example, slot). If the legacy design of the current paging opportunity is employed, the UE would detect the paging message different times for different numerologies within the 1 millisecond. Therefore, power consumption in some numerology would be greatly increased. Meanwhile, the paging capacity varies greatly due to the adoption of different numerologies.
- In order to solve the above design problem of paging when multiple numerologies are employed in the 5G NR, the present disclosure provides a solution, which determines the transmission opportunities of paging according to the numerology employed by the paging, thereby guaranteeing that the UE has a small difference in the complexity and power consumption of monitoring the paging message under different numerologies and that the paging capacity basically remains the same. It should be noted the embodiments of the UE of the present disclosure and the characteristics in the embodiments may be applied to the base station if no conflict is caused, and vice versa. Further, the embodiments of the present disclosure and the characteristics in the embodiments may be mutually combined if no conflict is caused.

InFIG. 3 , the radio protocol architecture of a UE and a base station device (gNB or eNB) is presented by three layers, which are alayer 1, alayer 2 and alayer 3 respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of a PHY layer. Thelayer 1 is called PHY 301 in this paper. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the UE and the gNB via the PHY 301. In the user plane, theL2 305 includes a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC)sublayer 303, and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers end at the gNB of the network side. Although not described inFIG. 3 , the UE may include several higher layers above theL2 305, such as network layer (i.e. IP layer) ending at a P-GW of the network side and an application layer ending at the other side of the connection (i.e. a peer UE, a server, etc.). The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 also provides a header compression for a higher layer packet so as to reduce a radio transmission overhead. The PDCP sublayer 304 provides security by encrypting a packet and provides support for UE handover between gNBs. TheRLC sublayer 303 provides segmentation and reassembling of a higher layer packet, retransmission of a lost packet, and reordering of a lost packet to as to compensate the disordered receiving caused by Hybrid Automatic Repeat Request (HARQ).
